IMG has posted a review of Legion Arena. Here's a clip from the review:

Legion Arena begins with a comprehensive tutorial campaign that should give even the most novice strategy gamers a quick handle on things. After said intro campaign, players then tackle the full-fledged Roman and Celtic campaigns. The game’s “story” unfolds by way of well-voiced narrated clips set against a world map and various still images of ancient Rome. The story is basically a history lesson, placing the player in the role of an up and coming general in the midst of the ancient world’s greatest military conflicts. While interesting and often informative, I never felt compelled to keep playing simply because I couldn’t wait to see where the story might go next. Legion Arena isn’t that sort of game, it’s not the next WarCraft. In Legion Arena, gameplay takes precedence over creative single-player story-telling. Personally, I play games to forget about reality, if only for a few hours. Still, history buffs should be pleased with Legion Arena’s single-player framework.
